Is it possible to parachute out of a 747

To add to this complexity, it is dangerous for the body to skydive at altitudes of more than 15, feet, and you have to take into consideration that the parachute alone may weigh as much as 40 lbs. Most airplane accidents occur on takeoff or landing. That fact alone makes having parachutes on planes impractical. In addition, since airplanes typically fly at around miles per hour and at roughly 35, feet, passengers would be unable to jump out of the plane if something bad did happen.

Nowadays, many small planes are equipped with parachutes, including whole-plane parachutes that have proven very effective. That way, only the passenger cabin would be braced during a freefall. Under this scenario, the wings and other components would detach to shed weight quickly. One conceptual blueprint even involves an aircraft designed to automatically sear off its wings using automated blades while the passenger-carrying sections would break off into parachute-equipped survival pods.

Implementing such an extreme safety measure, however, may not even be practical considering that aviation experts still question the effectiveness of using parachutes. For instance, a spokesman for the UK Civil Aviation Authority tells the BBC that even in the incredibly unlikely scenario that an airplane stalls in mid-air, there probably wouldn't be enough time for a parachute to deploy as the plane is moving at high speeds.

And since most fatal accidents occur during the takeoff or approach and landing phase of the flight, a scenario where a parachute might make a difference is rather remote. Unphased by skeptics, BRS is working, for now, to further develop the technology to a point where it can be used in private jets and other larger aircraft that seat up to 20 passengers.

However, I do hope scientists do come up with a similar escape device for crashing planes. The amount of innocent, and productive lives that are lost to these accidents is absurd The deployment can take place once the Aircraft gets in trouble and there is slim chances of recovery.

We have seen Airbus A like huge aircraft so why not develop something that can be accommodated into the Airframe hull later deployed by Pilots. I believe it won't take much of a space and it won't be that heavy system. It is time Engineers and Companies focus on safety as well rather then selling their products. Joe, Ontario Canada The immense technological knowledge that has emerged in our time gives me huge confidence that a safe means of ejecting out of the airplane when it is certain the plane will go down.

Often than not, all on board and airplane dies after a crash and this is frightening. Having read the unlikely chance of giving passengers parachute, an idea that once holds feasible in my mind, how about making the passenger sitting cubicle and ejectable and parachute enable section within the airframe. Like a group of 20 passenger in a sitting arrangement is placed in an ejectable frame, electronically goes off the airplane sensing mayday signals and deploys a parachute. In the movie "Airforce One", Harrison Ford acting US president in the movie was placed in a cubicles and ejected off the plane.

How about this technology implemented in commercial airlines. In combat jet planes, the pilot eject off with his seat, deploys a parachute to land safely. A model of this kind is possible I believe. Ernest Aghimien, Lagos Nigerua The immense technological knowledge that has emerged in our time gives me huge confidence that a safe means of ejecting out of the airplane when it is certain the plane will go down is conceiveable and more often than not, all on board an airplane will dies after a crash and this is frightening.

Having read the unlikely chance of giving passengers individual parachutes, an idea that once holds feasible in my mind, how about making the passenger sitting cubicle an ejectable and parachute enable section within the airframe. But even if you were trained to jump out of the plane and deploy a parachute, the conditions on—and around—a commercial airline hurtling through the sky at 35, feet aren't suitable for doing so, says Jim Crouch, director of safety and training for the U.

Parachute Association. There would be a chance of losing consciousness until descending into lower altitudes. It's dangerous for the human body to be exposed to such temperatures so immediately—scientists have suggested that the eyes, mouth, and nose would freeze almost instantly.

Wind chill isn't even factored in here.
